I think best option is to send us the base. We can pressure test to find exact pin hole leak and should be able to get it stopped. We do sell replacement bodies as well as all of the components to build a new chamber here: https://www.avastmarine.com/collecti...cement-parts-1

I do think we can fix it here though, so if you want to go that route, open a ticket on our site and we will get a RMA started for repair.
